Python: Concatenate element-wise three given lists

Python List: Exercise - 171 with Solution

Write a Python program to concatenate element-wise three given lists.

Sample Solution:

Python Code:

def concatenate_lists(l1,l2,l3):
    return [i + j + k for i, j, k in zip(l1, l2, l3)]
    
l1 = ['0','1','2','3','4'] 
l2 = ['red','green','black','blue','white']
l3 = ['100','200','300','400','500'] 

print("Original lists:")
print(l1)
print(l2)
print(l3)
print("\nConcatenate element-wise three said lists:")
print(concatenate_lists(l1,l2,l3))

Sample Output: 

Original lists:
['0', '1', '2', '3', '4']
['red', 'green', 'black', 'blue', 'white']
['100', '200', '300', '400', '500']

Concatenate element-wise three said lists:
['0red100', '1green200', '2black300', '3blue400', '4white500']

Python: Tips of the Day

Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:

Example:

def tips_check_prop(fn, prop):
  return lambda obj: fn(obj[prop])
check_age = tips_check_prop(lambda x: x >= 25, 'age')
user = {'name': 'Owen', 'age': 25}

print(check_age(user))

Output:

True
